NASA's Solar Dynamics Observatory captured sunspot AR3386 blast a long-duration X1.6-class solar flare and X1 flare. See time ...

After weeks of relative quiet, the Sun has erupted with a series of powerful solar flares, signaling a return to more active space weather conditions. Over the weekend, three M-class solar flares were ...

The sun has a bone to pick with Earth — and it’s not done yet. A colossal solar storm just zapped the daylight side of the planet, causing global blackouts and knocking out radio signals across Europe ...

After weeks of reduced activity, the sun erupted with three powerful flares on a single day. That could send solar flares toward Earth, impacting electronics and making it possible to view the ...

Strong solar flare and geomagnetic storm watch may bring spectacular northern lights to the continental US, with best viewing ...

Beautiful yet dangerous solar flares that erupt from the sun could be as hot as 180 million degrees Fahrenheit, researchers say. That's more than six times hotter than solar physicists previously ...

Solar flares can be many times the size of Earth and can damage things like satellites. A new study suggests that eruptions from the sun can be even hotter than researchers thought. Solar flares are ...

The M4.4 solar flare unleashed a coronal mass ejection (CME) into space — and Earth might just receive a glancing blow. Sunspot region 4168 is certainly making quite a name for itself! Earlier this ...

As the sun geared up to spit a powerful solar flare into space, NASA scientists snapped huge loops of plasma leaping from the sun's surface. These spectacular solar structures, known as coronal loops, ...

Particles within solar flares may reach temperatures more than six times higher than scientists previously believed—offering an explanation to a long-standing astrophysical puzzle about the Sun. This ...

Solar flares are intense bursts of light and particles from the sun. While they can pose hazards for things like satellites, these flares are also beautiful, dramatic and incredibly hot. NPR's Nell ...
